The best part about this game was the coconut-throwing monkies and laser cows that would appear if you played around with the buttons at the bottom of the interface.
You could edit the raw data of the EXE file to change the text on the loading screen. Everyone in my school at the time made the loading screen call the game "Fucker: Call of the Hackers"
I didn't really get into overhead shooters on the PC because I didn't own a gamepad until much later, and they weren't as fun with the keyboard. Clearly I missed out, because this looks better than most of the console ones I liked.
